Abstract
Objective To explore the high-frequency ultrasound features of keratoacanthoma.Methods A retrospective analysis was conducted on the high-frequency ultrasound imaging find-ings of 52 cases of keratoacanthoma confirmed by postoperative pathology at the First Affiliated Hospital of Henan University of Science and Technology from October 2022 to July 2024.The characteristic changes were summarized.Results Keratoacanthoma was more common in males(73.08％)and predominantly occurred on the head and face(57.69％),followed by the limbs(28.85％).The lesions protruded above the body surface(96.15％),with surface ulceration observed in some cases(51.92％).High-frequency ultrasound revealed hypoechoic nodules(100％)with regular(88.46％)or irregular(11.64％)shapes.The internal echogenicity was homogeneous(57.69％)or heterogeneous(42.31％),with punctate calcifications seen in heter-ogeneous cases.All lesions were in the dermis(100％),with either well-defined boundaries(61.54％)or unclear margins(38.46％).Posterior echo attenuation was observed in some cases(51.92％).The growth patterns included parallel(38.46％),inward(34.62％),and expan-sive(26.92％)types,with Alder grades ranging from 0 to Ⅲ.Conclusions The ultrasound fea-tures of keratoacanthoma demonstrate distinct characteristics.High-frequency ultrasound enables detailed visualization of critical information,including internal and surrounding tissue echotexture,infiltration depth,and growth patterns,providing valuable evidence for preoperative diagnosis and staging.关键词
